Abstract

A tapered roller bearing comprising an outer race (14), a pair of axially adjacent inner races (10A, 10B), and two cages (13A, 13B) interposed between the inner and outer races to retain two sets of rollers (12A, 12B). The radially outer surface of each inner race has, close to the end facing the centre (X) of the bearing, a groove (20A, 20B) able to receive a respective plurality of radially inwardly projecting portions (22A, 22B) of the parts of the cages disposed close to the centre (X) of the bearing so that the cages retain the rollers on the respective inner races during the handling and assembly steps which precede mounting of the sub-units (10A, 13A, 12A; 10B, 13B, 12B) comprising the inner race, cage and rollers into the outer race (14).
